Is it possible to damage an FPGA using a configuration file for wrong FPGA type?

I have damaged the EP4CE40F29 FPGA on several boards. The symptom is that the FPGA short-circuits the 3.3V power supply for the IO-Banks 1, 7 and 8 (3.3V power supply limits at 0.2V dilivering about...

Hi,


  • Wrong Configuration file will not causes damage to the device.
  • What do you mean by using standard software? What software did you used?
  • Is there any changes when you change the devices?
  • The power regulator might not functioning correctly and overpower the device then causing damage.

Regards,

Aiman

Thank you for the answer.

  • With "standard software" I mean the our software that is used to operate the system. The code that is loading the configuration file to the FPGA seems to be "old" (some years). Nobody in the software development team knew any details about it.
  • Except for soldering the EP4CE40F29 to the same position as the EP4CE30F29, there are no changes on our board.
  • I had a look at the power supplies already. I did not see overpowering (too high voltage) problems.
    Due to a problem in the system, the 3.3V power supply for the IO-banks was not present, when loading the configuration file. Can this be the cause of the damage?
